Cardinals right-hander Joe Kelly has been on the disabled list since mid-April with a hamstring injury and it sounds like he’s not close to rejoining the rotation.

Rick Hummel of the St. Louis Post Dispatchreports that Kelly hasn’t been cleared to throw a bullpen session or do any running following a “flareup” 10 days ago. Kelly told Hummel that he’s trying to be cautious in order to avoid aggravating the hamstring injury again and “be out the rest of the year.”

Triple-A call-up Tyler Lyons was doing relatively well stepping into the rotation in place of Kelly until Monday, when he allowed nine runs against the Cubs to send his ERA from 3.43 to 6.12. Based on Kelly’s status Lyons seems likely to hang onto a starting gig until at least mid-June.
